sudo dnf install -y sysstat iotop htop stress sysbench

# CPU Performance Baseline:
# 1. CPU information and capabilities
lscpu
cat /proc/cpuinfo | grep -E "processor|model name|cpu MHz|cache size" | head -20

# 2. CPU stress test
stress --cpu $(nproc) --timeout 60s &
# Monitor during test:
top -d 1

# 3. CPU benchmark
sysbench cpu --cpu-max-prime=20000 --threads=$(nproc) run

# 4. Context switching performance
vmstat 1 10   # Monitor context switches (cs column)

# Memory Performance Baseline:
# 1. Memory information
free -h
cat /proc/meminfo | grep -E "MemTotal|MemFree|MemAvailable|Cached|Buffers"

# 2. Memory bandwidth test
sysbench memory --memory-total-size=10G --memory-oper=read run
sysbench memory --memory-total-size=10G --memory-oper=write run

# 3. Memory latency test
lat_mem_rd -P 1 -W 1 1024 64   # If lmbench installed

# Disk I/O Performance Baseline:
# 1. Disk information
lsblk
df -h
cat /proc/mounts | grep -v tmpfs

# 2. Sequential read/write test
dd if=/dev/zero of=/tmp/testfile bs=1G count=1 oflag=dsync
dd if=/tmp/testfile of=/dev/null bs=1G count=1

# 3. Random I/O test
sysbench fileio --file-total-size=5G prepare
sysbench fileio --file-total-size=5G --file-test-mode=rndrw --time=60 run
sysbench fileio cleanup

# Network Performance Baseline:
# 1. Network interface information
ip link show
ethtool eth0   # Interface capabilities

# 2. Network throughput test (requires iperf3 on both ends)
# Server: iperf3 -s
# Client: iperf3 -c server_ip -t 60

# 3. Network latency test
ping -c 100 8.8.8.8 | tail -1

net.ipv4.tcp_wmem = 4096 65536 134217728

# TCP congestion control algorithm
net.ipv4.tcp_congestion_control = bbr

# Enable TCP window scaling
net.ipv4.tcp_window_scaling = 1

# TCP Fast Open
net.ipv4.tcp_fastopen = 3

# Increase connection backlog
net.core.netdev_max_backlog = 5000

sudo sysctl -p /etc/sysctl.d/99-performance-tuning.conf

# Verify settings:
sysctl vm.swappiness
sysctl net.ipv4.tcp_congestion_control
sysctl net.core.rmem_max

CPU Performance Optimization:

# 1. CPU Governor Configuration
# Check current governor:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

# Set performance governor:
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# Make permanent:
sudo dnf install kernel-tools
cat | sudo tee /etc/default/cpupower << 'EOF'
# CPU governor settings
CPUPOWER_START_OPTS="frequency-set -g performance"
CPUPOWER_STOP_OPTS="frequency-set -g ondemand"
EOF

sudo systemctl enable cpupower

# 2. CPU Affinity and NUMA Optimization
# Check NUMA topology:
numactl --hardware
lscpu | grep NUMA

# Example: Bind process to specific CPU
taskset -c 0-3 command    # Use CPUs 0-3
numactl --cpubind=0 --membind=0 command  # Use NUMA node 0

# 3. IRQ Balancing
# Install irqbalance:
sudo dnf install irqbalance
sudo systemctl enable --now irqbalance

# Check IRQ distribution:
cat /proc/interrupts

# Manual IRQ affinity (if needed):
echo 1 | sudo tee /proc/irq/24/smp_affinity  # Bind IRQ 24 to CPU 0

# 4. Transparent Huge Pages
# Check current setting:
cat /sys/kernel/mm/transparent_hugepage/enabled

# Disable for database workloads:
echo never | sudo tee /sys/kernel/mm/transparent_hugepage/enabled
echo never | sudo tee /sys/kernel/mm/transparent_hugepage/defrag

# Make permanent:
cat | sudo tee /etc/tmpfiles.d/hugepages.conf << 'EOF'
w /sys/kernel/mm/transparent_hugepage/enabled - - - - never
w /sys/kernel/mm/transparent_hugepage/defrag - - - - never
EOF

Memory Optimization:

# 1. Memory Allocation Tuning
# Configure memory zones:
echo 1 | sudo tee /proc/sys/vm/zone_reclaim_mode

# 2. Huge Pages Configuration (for databases)
# Calculate huge pages needed (example for 8GB):
HUGEPAGE_SIZE=$(grep Hugepagesize /proc/meminfo | awk '{print $2}')
PAGES_NEEDED=$((8*1024*1024/$HUGEPAGE_SIZE))

# Set huge pages:
echo $PAGES_NEEDED | sudo tee /proc/sys/vm/nr_hugepages

# Make permanent:
echo "vm.nr_hugepages = $PAGES_NEEDED" | sudo tee -a /etc/sysctl.d/99-hugepages.conf

# 3. NUMA Memory Policy
# Check NUMA memory usage:
numastat

# Set NUMA policy for applications:
numactl --preferred=0 command   # Prefer NUMA node 0

# 4. Memory Compaction
# Enable automatic memory compaction:
echo 1 | sudo tee /proc/sys/vm/compact_memory

# 5. Memory Cgroup Optimization
# Create memory cgroup for critical applications:
sudo mkdir /sys/fs/cgroup/memory/critical
echo $((16*1024*1024*1024)) | sudo tee /sys/fs/cgroup/memory/critical/memory.limit_in_bytes

Amazing! 🌟 Kernel and system optimization complete!

🌟 Step 3: Storage and I/O Optimization

Maximize disk performance! ⚡

Disk I/O Scheduler Optimization:

# 1. Check current I/O scheduler:
cat /sys/block/sda/queue/scheduler

# 2. Optimize schedulers by disk type:
# For SSDs (use noop or none):
echo none | sudo tee /sys/block/nvme0n1/queue/scheduler
# For traditional HDDs (use deadline or mq-deadline):
echo mq-deadline | sudo tee /sys/block/sda/queue/scheduler

# 3. Make permanent:
cat | sudo tee /etc/udev/rules.d/60-ioschedulers.conf << 'EOF'
# Set I/O scheduler based on drive type
# SSDs use none, HDDs use mq-deadline
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="none"
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="1", ATTR{queue/scheduler}="mq-deadline"
ACTION=="add|change", KERNEL=="nvme[0-9]n[0-9]", ATTR{queue/scheduler}="none"
EOF

# 4. Optimize I/O queue depth:
echo 32 | sudo tee /sys/block/sda/queue/nr_requests

# 5. Disable disk read-ahead for random I/O workloads:
blockdev --setra 256 /dev/sda  # Reduce read-ahead

File System Optimization:

# 1. Mount Options for Performance
# Create optimized fstab entries:
cat | sudo tee -a /etc/fstab << 'EOF'
# Performance-optimized mount options
# For ext4 filesystems:
/dev/sda1 /data ext4 defaults,noatime,nodiratime,data=writeback,barrier=0,nobh 0 2

# For XFS filesystems:
/dev/sdb1 /logs xfs defaults,noatime,nodiratime,logbufs=8,logbsize=256k,largeio,inode64 0 2
EOF

# 2. Ext4 Optimization
# Optimize existing ext4 filesystem:
sudo tune2fs -o journal_data_writeback /dev/sda1
sudo tune2fs -O ^has_journal /dev/sda1    # Remove journal for read-heavy workloads
sudo e2fsck -f /dev/sda1                  # Check filesystem after journal removal

# 3. XFS Optimization
# Format XFS with performance options:
sudo mkfs.xfs -f -d agcount=4 -l logdev=/dev/sdc1,size=256m /dev/sdb1

# 4. Disable access time updates globally:
cat | sudo tee /etc/tmpfiles.d/noatime.conf << 'EOF'
# Mount all filesystems with noatime
f /etc/fstab - - - - defaults,noatime
EOF

# 5. File System Caching
# Increase buffer cache:
echo 'vm.vfs_cache_pressure = 50' | sudo tee -a /etc/sysctl.d/99-performance-tuning.conf

# 6. Tmpfs for Temporary Files
# Mount /tmp in RAM:
echo 'tmpfs /tmp tmpfs defaults,nodev,nosuid,size=2G 0 0' | sudo tee -a /etc/fstab

RAID and LVM Optimization:

# 1. RAID Performance Tuning
# Check RAID status:
cat /proc/mdstat

# Optimize RAID read-ahead:
sudo blockdev --setra 65536 /dev/md0

# Set optimal stripe cache size:
echo 8192 | sudo tee /sys/block/md0/md/stripe_cache_size

# 2. LVM Performance Optimization
# Create performance-optimized LV:
sudo lvcreate -L 100G -n data_lv volume_group \
    --stripes 4 --stripesize 256k

# Optimize LVM metadata:
cat | sudo tee -a /etc/lvm/lvm.conf << 'EOF'
devices {
    # Optimize device scanning
    scan = [ "/dev/disk/by-id", "/dev/mapper", "/dev" ]
    write_cache_state = 0
}
allocation {
    # Optimize allocation
    cling_tag_list = [ "@*" ]
}
EOF

# 3. SSD Optimization
# Enable TRIM for SSDs:
sudo systemctl enable fstrim.timer

# Manual TRIM:
sudo fstrim -av

# Check SSD health:
sudo smartctl -a /dev/nvme0n1 | grep -E "Temperature|Wear_Leveling|Reallocated"

🚨 Fix Common Problems

Performance troubleshooting guide! 🔧

Problem 1: High CPU Usage and Load

Solution:

# Identify CPU bottlenecks:
# 1. Find CPU-intensive processes
top -bn1 | head -20
ps aux --sort=-%cpu | head -10

# 2. Check CPU frequency scaling
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
# Set to performance:
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# 3. Analyze CPU usage patterns
sar -u 5 12  # CPU usage every 5 seconds for 1 minute
mpstat -P ALL 5  # Per-CPU statistics

# 4. Check for CPU throttling
grep -i "cpu clock throttled" /var/log/messages
# Check CPU temperature:
sensors | grep Core

# 5. Optimize CPU-bound processes
# Use nice/ionice to adjust priorities:
renice -10 $(pgrep important_process)
ionice -c 1 -n 4 $(pgrep important_process)

# 6. Enable CPU performance governor permanently:
sudo dnf install kernel-tools
sudo systemctl enable cpupower
echo 'CPUPOWER_START_OPTS="frequency-set -g performance"' | sudo tee /etc/default/cpupower

Problem 2: Memory Pressure and Swapping

Solution:

# Fix memory issues:
# 1. Identify memory hogs
ps aux --sort=-%mem | head -10
smem -r -k  # Install: sudo dnf install smem

# 2. Reduce swappiness
echo 1 | sudo tee /proc/sys/vm/swappiness
echo 'vm.swappiness = 1' | sudo tee -a /etc/sysctl.conf

# 3. Clear system caches
sync && echo 3 | sudo tee /proc/sys/vm/drop_caches

# 4. Optimize dirty pages
echo 15 | sudo tee /proc/sys/vm/dirty_ratio
echo 5 | sudo tee /proc/sys/vm/dirty_background_ratio

# 5. Check for memory leaks
# Monitor process over time:
while true; do
    ps aux | grep process_name | awk '{print $6}'
    sleep 60
done

# 6. Add more swap if needed
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

# 7. Configure huge pages for large applications
HUGEPAGE_SIZE=$(grep Hugepagesize /proc/meminfo | awk '{print $2}')
PAGES_NEEDED=$((4*1024*1024/$HUGEPAGE_SIZE))  # 4GB
echo $PAGES_NEEDED | sudo tee /proc/sys/vm/nr_hugepages

Problem 3: Disk I/O Bottlenecks

Solution:

# Optimize disk performance:
# 1. Check I/O wait times
iostat -x 1 5
iotop -o  # Show only processes doing I/O

# 2. Optimize I/O scheduler
# For SSDs:
echo none | sudo tee /sys/block/nvme0n1/queue/scheduler
# For HDDs:
echo mq-deadline | sudo tee /sys/block/sda/queue/scheduler

# 3. Increase read-ahead for sequential workloads
blockdev --setra 8192 /dev/sda

# 4. Mount with performance options
# Add to /etc/fstab:
# /dev/sda1 /data ext4 defaults,noatime,nodiratime 0 2

# 5. Enable write-back caching (if safe)
hdparm -W 1 /dev/sda

# 6. Optimize file system
# For ext4:
tune2fs -o journal_data_writeback /dev/sda1
# For XFS, remount with:
mount -o remount,noatime,nodiratime,logbufs=8 /dev/sda1

# 7. Check disk health
smartctl -H /dev/sda
smartctl -a /dev/sda | grep -E "Reallocated|Pending|Uncorrectable"

Problem 4: Network Performance Issues

Solution:

# Network optimization:
# 1. Test network performance
iperf3 -s  # On server
iperf3 -c server_ip -t 60  # On client

# 2. Optimize TCP parameters
cat | sudo tee /etc/sysctl.d/99-network-performance.conf << 'EOF'
# Network performance optimization
net.core.rmem_max = 134217728
net.core.wmem_max = 134217728

net.ipv4.tcp_wmem = 4096 65536 134217728
net.ipv4.tcp_congestion_control = bbr
net.core.default_qdisc = fq
net.ipv4.tcp_mtu_probing = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
EOF

sudo sysctl -p /etc/sysctl.d/99-network-performance.conf

# 3. Check network interface settings
ethtool eth0
# Enable features:
ethtool -K eth0 rx on tx on sg on tso on gso on

# 4. Optimize network card queue
echo 4096 | sudo tee /sys/class/net/eth0/queues/rx-*/rps_cpus

# 5. Check for packet loss
ip -s link show eth0
# Look for errors, dropped packets

# 6. Optimize application socket buffers
# In application config, increase:
# SO_RCVBUF and SO_SNDBUF to 16MB or higher
